What is the primary characteristic that distinguishes a 'count-controlled loop' from an 'event-controlled loop'?
What is the primary characteristic that distinguishes a 'count-controlled loop' from an 'event-controlled loop'?
- Count-controlled loops can only be implemented using 'while' statements.
- Count-controlled loops are always faster than event-controlled loops.
- Count-controlled loops iterate a specific number of times, while event-controlled loops continue until a condition is met. (correct)
- Event-controlled loops are used exclusively for handling user input.
In the context of algorithm design, what does a 'concrete step' represent?
In the context of algorithm design, what does a 'concrete step' represent?
- A step that can be skipped without affecting the outcome of the algorithm.
- A step that is only relevant to a specific programming language.
- An abstract, high-level description of a task.
- A detailed action that precisely specifies how to perform a task. (correct)

Study Notes
- An array refers to a collection of items stored at contiguous memory locations, where each item can be accessed using an index.
- Binary search represents a search algorithm used to locate the position of a target value within a sorted array by repeatedly dividing the search interval in half.
- Bubble sort is a sorting algorithm that steps through a list, compares adjacent elements, and swaps them if they are in the wrong order.
- A concrete step refers to a detailed action in an algorithm that specifies how to perform a task.
- A count-controlled loop is a loop that repeats a specific number of times, controlled by a counter variable, an example is a "for" loop.
- Desk checking denotes a manual method of reviewing the logic of a program using a pencil and paper instead of a computer.
- An event-controlled loop is a loop that continues to execute until a specific condition or event occurs, like user input or a sensor reading.
- Heterogeneous describes a collection of items that are of different types.
- Homogenous describes a collection of items that are all of the same type.
- Index signifies a numerical representation of an element's position within an array or a list.
